Issue:
When i brought this videocon tv it has inbuilt hd setup box, it was showing hd channels, even still 31st december 2018, i was viewing the hd channels. But now hd channels are not available for selection for me. I have checked with customer care, in mobile application and on website of d2h, because of this i am not able to view hd channels. (I can view only one hd channel currently.)
Customer care (D2h) is saying that my setup box is not hd, but then how i was able to view the hd channels earlier still december 2018?
Also i checked with tv supplier and d2h operator of videocon he is saying that set box is hd.
